IDSL/DDS Trouble Code

The IDSL/DDS system provides a quick diagnosis in

the case of a circuit condition where continuity is

broken. The trouble code type received by a tester

determines whether the open condition is occurring on

the local loop or at the customer premises. In the

event of an open conductor or disconnected 2-wire

loop, the U-BR1TE IV transmits a Mux-Out-of-Sync

trouble code (MOS 9Ah) into the network as shown in

Figure 11. During a similar out-of-service condition

at the customer premises, the IDSL OCU-R transmits

Abnormal Station Code (ASC 9Eh) upstream into the

network as shown in Figure 11.

4. MAINTENANCE

The U-BR1TE III does not require routine

maintenance for normal operation.
